STEM WINDING AND SETTING WATCl i.

SPECIFICATION forming part of Letters Patent No. 396,777, dated January 29, 1889. Application filed April 12, 1888. Serial No. 270,444. (No model.

To (rZZ whom it may concern.-

Be it known that I, OSCAR l1. S'lEDMAN, of

Ravenna, in the county of Portage and State I of Ohio, have invented certain new and useful Improvements in Stem Yin ding and Setting Vatches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in stem winding and setting watches; and it consists in the combination of an elnlwise-moving winding-stem, a spring-actuated. sliding bar provided with a projection, and a pivoted spring-actuated yoke carrying the winding and setting wheels and provided with an in.- clined, surface, against which the projection strikes, as will be more fully described hereinafter.

The object of myinvention is to operate the pivoted yoke by means of a spring-act uated sliding bar, which is operated entirely by the wiinling-stem, and which bar moves the yoke into position for setting the hands and locks it.

Figures 1 and 2 are side elevations of my invention taken from one side of the pillarplate and showing the parts in different positions. Figs. 3 and l are similar views taken from the opposite side of the pillar-plate, and also showing the parts in different positions.

A represents the pillar-plate, andB the en dwise-inovin stem, which plays back and forth in the pendent t. In the inner end of this winding-stein B is formed a groove, D, and the end of this stem preferably made rounding or tapering, as may be preferred. Placed in directcontact with the pillar-plate, and held in position by a suitable guide, is t he endwisesliding bar E, which has its innerend beveled, so as to be operated upon by the winding-stem B when the stem is forced inward. 0f the stem when forced inward strikes against the beveled inner end of the bar E and forces it endwise against the pressure of the spring F until the point of the bar catches in the groove upon the inner end of the stem. In this position the bar is moved outward as far The end 1 to lock the yoke in position.

as it. can move and against the PIPSSHI'C of the spring F. When the stem is drawn outward for the purpose of setting thehands, the inner end of the bar becomes detached from the groove D, and then the spring forces the bar inward, as shown. The distance the bar E is moved inward by the spring is regulated by a stop, and the distance the bar ismoved out ward is regulated by the winding-stem.

Formed on. the inner end of this endwisemoving bar E is a stud orp rejection, G, which passes through a slot, II, in thepillar-plate, so as to operate upon the pivoted yoke I, which has the spring .I applied to one end. This yoke carries the winding and setting wheels in the usual manner and turns upon its pivot sufficiently far to bring either the winding or I setting wheels into operation, as may be desired. In the top ed ge of thisyrjikelis formed the inclined surface Ii, against which the pro jection G, upon the sliding bar E, strikes for the purpose of turning theyoke upon its pivot sufficiently far to bring the hand setting wheels into operation. \Yhen the bar-E is moved outward by the \vinding stem.ll, the projection does not come in contact with the inclined surface L, but leaves the yoke free to have a vibratory movement while the watch is being wound. \Yhen, however, the stem I3 is drawn outward, the spring I? forces the bar E inward and then the projw-tjion (t strikes against the inelincd surface I. and causes the yoke to turn upon its pivot sufficiently far to bring the handsetting wheels into operation, and then moves along the straight upper edge, 0, of the yokefarenough When the yoke is turned upon its pivot by the projection G, the pressure of the spring .I against the end of the yoke is overcome; but when the endwise-moving bar I is foretal outward by the stem the spring .I is left free to operate the yoke to throw it into position ready for winding. The spring l ,being more powerful than the spring .l, entirely ovrreomes its pressure when the winding-stem is withdrawn.

Idonotlimit myself to any particular uni-ans or mechanism for-locking the winding-stem in position when forced inward, as this may be Any means heretofore devised varied at will.

may be applied to the stern that may be desired.

Having thus described my invention, 1 claim- 1. The combination of the endwise-inoving winding-stem, the endwisemoving bar, a spring applied directly to the end of the bar for moving both the bar and the yoke, and the pivoted spring-actuated yoke carrying the winding and setting wheels, the barbeing provided with a projection which extends through an opening in the pillar-plate and makes direct contact with the yoke, substantially as shown.

2. The combination of the ein'lwise-moving winding-stem, the spring-actuated endwisemoving bar provided with a projection, the

pivoted spring-actuated yoke carrying the winding and setting wheels and provided with an inclined surface, against which the projection upon the endwiseqnovingbar strikes, substantially as described.

The endWise-moving winding-stem provided with a groove near its inner end, in combination with the endwise-sliding bar having a beveled point to catch in the groove and lock the stem in position and provided with a projection at its outer end to operate the yoke, and the spring F, applied directly to the end of the bar, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

O. F. STEDMAN.
